[Q] LG G4 H815 Not rotating/Accelerometer stuck

I randomly realized my G4 wasn't rotating the screen anymore and I have since tried everything - factory resetting, calibrating the sensor (doesn't work) and even the banging phone on table method, none are successful.
This may indicate that it is a hardware issue but if I hold the phone landscape and open the camera the buttons do rotate, but if I rotate whilst already inside the app nothing changes so I'm not exactly sure what is going on. When I use the app CPU-Z to track the accelerometer value it stays static until I turn the screen off and move the phone a bit, when I turn it on the value changes again but stays still.
Any idea what the cause is??

does booting into safe mode make any difference (i know you said factory reset, but I'm curious).
Also, probably won't, but is there any difference whilst the phone is charging?

Throwing this out there. Did you debloat? On the Samsung models, if you uninstall the Hub app, rotation gets broken for some weird reason. I don't know what that would be on the G4, but maybe? Just a random guess.

I'll try booting into safe mode, and there's no difference while charging.

I believe I did remove a few apps but since I factory reset and flashed a fresh image I believe they should be restored?

Not necessarily. I know a factory reset doesn't restore any previously removed apps, and flashing factory a fresh image depends on how it's flashed I've discovered. Only a CSC restores the phone to factory specs, while other methods didn't for me.

Safe mode didn't help, and I actually don't know which ones I removed but they looked pretty normal, how do I check or compare vs stock?

I think I recall seeing a debloat list somewhere. See if you can find it and compare what you've got. I'm not saying this is the problem, but it could be.

Yeah I found a few lists but they only have apps that are safe to remove and don't warn or mention possible ones that cause problems which I may have already removed

I had the exact problem a few weeks ago, thought my hardware was already flaking. Don't remember what I did to get it working, but it wasn't overly complex.. Rebooting didn't help, I think I pulled the battery, waited a bit, and then rebooted and then went to calibration from there.
Do you happen to have xposed installed by the way?

Hey thanks for your reply, I am trying now the battery pulling method, did you then calibrate through the sensor in display settings?
And yeah I do, hmm not sure if it stopped working after that actually.. but I remember after I flashed a fresh .kdz even without xposed it still doesn't work.

Yea would have been the calibration from the regular settings.
As for xposed, flashing a kdz will keep user data and settings.. It might have been gravitybox causing the issue for me, which if you uninstall that, reboot and reinstall it, might help. Same goes for any other modules you had enabled.

Oh yeah it did but I factory reset as well so... I never installed gravitybox since I heard there were some problems with it but I'll see if there are any modules causing issues.

Yeah I have I don't even know there are signs that point towards it being a hardware or a software issue tbh.

Problem happened to me too. Started yesterday, sometimes worked, sometimes stuck on portrait.
Shutting down and pulling the battery for a few seconds seems to do the trick. It works properly now..

Have you been used apps which could calibrate the accelerometer before?
etc. some games that needs to be controlled by rotating the phone on its axis..

Me? Not that I know. Some new apps yes, but still proper screen rotation.

This problem happened on my g4 today...

Stock ROM?

LG 4 not rotating??
quick fix which worked for me was just take the battery out, wait 30 seconds, put back in switch on and problem solved...
hope this helps guys.... regards Steve

Recent apps not showing

Whenever I click on recent apps the phone shows no recent apps..after I first encountered this issue I did a factory reset and it worked for 24 hrs and then I have the same issue... Phone is on latest update.

I also faced this issue. I could pinpoint to some changes made in my Settings, and after I reverted these I got it all back. Now which really effects is a wide window, but I could broadly point it to display settings and few apps which I had disabled. So, you may try re-enabling any disabled apps and reverting settings one-by-one.
Splendid colour settings was the last I enabled, but now I haven't faced this issue again.

My issue was resolved by but it happened all of a sudden

I am trying to replicate the issue, if I make some headway I will post it.

Dont know how its happen,when phone keep in safe mode..and after restarting from safe mode its working now.

I have faced this issue twice. I am not sure on the resolution. I personally had to reset it both the times to get it working. As far as the cause goes... The first time I faced the issue when I tried to install XDA gesture navbar app. Even after uninstalling the app the recent button didn't work. I can confirm before that the recent button was working.
The second time was the next day itself. I factory resetted the phone and I was on my way to office in bus when I decided to install a oreo launcher 'Launcher oreo 8.1' which i used flawlessly on my moto g5 plus. And after installation of oreo launcher and setting it as default launcher my recent apps was gone. The problem started occuring. As you may have guessed uninstalling it didint help. After that I have not installed any launchers and everything is working fine. This weekend I will try to recreate the scenario and see if I can find any resolution to this. I thought it was a unique problem to my device and it occurred for the tweaking and everything. But now it seems that other people are also facing these issues with different triggers.

I am facing the same issue. It happened all of a sudden today. I did not install anything new.
Any tips to resolve this except from factory reset?
Please help!

Update
Wokring now. Switched to safe mode and uninstalled zenui dialer, weather and launcher apps to old version.
Not sure which app is causing this.

Booting into safe mode works. First power off normally, then hold power button to power on, release it when the Asus logo comes and hold down volume down button( dont press power button). Then use the recent apps button and restart normally.
I faced the same issue after the OTA update but this fix has been working for the last 5 hours just fine.

for rebooting in safe mode,press and hold power button>press and hold on power off option>pop up appear to go in safe mode

Disable zenmotion and reboot. Worked for me. What a broken phone!

Lots of different small issues

Hi all
I have been using this phone for a month, and I have experienced a lot of different small issues, I hope someone may have solution to them.
Phone:
Mi A2 Lite, rooted (Magisk) Android one pie, January update. Has a screen protector.
Apps:
Here are some apps that I think may cause the issue that I mention below, these apps are Nova and datally. Really can't think of a third one, I don't use any cleaning app or battery performance app.
Issue:
1. Typing experience is horrible. Using stock google input, the keyboard is not very sensitive and accurate. The letter just can't be recognized even though I am sure I have pressed the key and pressed the right key. So my typing is really slow, the key doesn't display immediately (it does seem to have a delay), and for some reason I always type wrong and missing some letters, so gotta use backspace a lot.
2. It always wakes up randomly in my pocket, so I may take the phone out with torch on and airplane mode on without my awareness.
3. When I am on a call, I can accidentally press some random on screen keys.
4. The background apps AWALYS get killed, even though I have turned the battery optimization off globally, and the individual apps that I never want to be killed.
5. Messaging service apps have huge delay when delivering the notification. It may only show when I open the app. Used PNF app but couldn't fix the problem.
Does anyone have the same issue and know the fix?
I hope it is only the software problem (Pie system) and maybe I can fix it by flashing a better rom, but I don't seem to find a stable official custom ROM for Mi A2 Lite (even lineage OS is unofficial)
Many thanks

You have battery optimization off? any battery improvement app? I think all these is because the 'intelligence' in Android is playing up, it doesn't understand exactly how we use the app. However, even have it turned off, the problem exists....

Uresponsive black screen after updating to Android 10

After updating to 10, a few times a day my phone becomes completely unresponsive. Since the screen is off, I'm not even sure if the phone is powering off. I've flashed the factory image to see if starting clean would fix it, but that didn't work. Anybody else experiencing this?

No, but you may be installing an app that is causing it. Try replicating the issue in safe mode. Ruling that out, if you have done a clean install using the full image (not ota) and allowed it to wipe your data there is not much more to do before contacting Google. A clean install restores your phone to its "out of the box" state. If the problem persists, it is likely hardware related. You can try a factory reset from the stock recovery... that is the first thing they will insist you do before processing an RMA.

I didn't have the issue on Pie and haven't installed any additional apps. It mainly happens after I haven't used the device for a while. It feels like it won't wake up so I have to hold the power button to force a reboot.

Yes.
I was just peaking to a buddy with a 2xl and he is having the same issue since 10.

I have an issue where after about two day of it being on it will start to stutter, and then after a couple hours it reboots itself. It's done it since 10 was released. Never had an issue on 9. Now I proactively reboot it once I notice the stuttering. Kind of sucks since 9 was super stable for me. No new apps, and no settings were changed. Just updated to 10, and it started. Kind of like memory is leaking causing it to stutter/freeze, but the last patch they said they fixed the leak. Guess not.

I just had a random reboot while taking my dog for a walk. Was only listening to SiriusXM. Think I'm going back to Pie until Google gets the kinks ironed out on 10.

https://support.google.com/pixelphone/thread/14074635?hl=en

Booted into safe mode last night and had to force a reboot this morning to get the screen to respond. This is definitely an issue with 10 and not an app. I'm going back to Pie since having my phone turn off every night is unacceptable, especially since my phone is my alarm clock.

I took the OTA before setting up my new P3XL on A10 and don't have any issues. You might try wiping data then restore apps without data.

I flashed the A10 Oct factory image and wiped data. Still have the issue. The only thing that fixes it is going back to Pie.

So this happened to me twice now since being on 10. My screen would go black while using the phone, and then the phone would be unresponsive, so I would need to force a reboot, but after the Google splash screen it goes into recovery, and this message shows "Could not load Android OS. You can try again, or factory reset.". I did "Try again" both times, and it booted fine. Really irks me since I can't afford to do a factory reset since I use a lot of apps that have special info in them (Like Google Auth App that has many devices I need, and resetting I would have to redo every device). I hope Google can fix these issues with the next update.

I think my issue is due to the sensor bug that was introduced in 10. I have disabled the sensors on my phone and it hasn't froze since!! Hopefully Google fixes on the Nov update.

I'm having the issue that after my screen turns off, after a certain amount of time, I cannot get it to turn back on. The phone is still on, but is unresponsive to my input. I have to hard reset.
I have tried reflashing, and tried disabling sensors. I did not have an issue with the 10 September updated, but since updating to the November update, I had the issue non-stop all day.
Platform-Tools fully updated, not using gesture navigation, but the 2-button.

@MeetFace, yes! Same here since the November update. Something isn't right.

I'm still dealing with the black screen issue. Nov update didn't fix it.
https://issuetracker.google.com/issues/143288447

Update, I read in a thread somewhere that disabling darkmode fixed it for one person (rando I know).
I created a tasker script that disables darkmode once the screen shuts off, and enables it when it turns back on. So far, no BSOD this morning (4 hrs)
FWIW

Question Issues afteratest update

S21fe updated to UI5.
Couple of issues.... Fingerprint reader sometimes doesn't work when phone hasn't been used for some time. When it happens I need to double tap the screen to wake it up and then scan my fingerprint again.
Also "back" gesture (where I swipe up from the right bottom of the screen) sometimes instead of going back brings up the list of background apps.
Both issues very annoying.
Anyone else experienced anything similar?

Try clearing the system cache. Double check all settings. If that flaws things get more complicated...
A factory reset may be needed, but hard to say if it will resolve the issues. Someone will need to try the latter if the former doesn't work. A global reset of settings is a less drastic option but it may not be enough and still take a lot of time.
This is one reason why I spurn upgrades on a platform that's fulfilling its mission. Lol, I'm still using UI 1.5, no glaring issues.
Unfortunately with latter versions an upgrade may resolve flaws in earlier post >1.5 variants. Tough choice once you are on Android 11 as there's no roll back on stock Samsung's for that. I wasn't locked into using 11 on my N10+'s and never will load it. 12 is even worse.
Roll back is an option for you if bootloader wasn't upgraded too. Eventually Samsung will fix it if it's a firmware/software glitch but don't hold your breath for that

That may not be enough if going from 11 to 12, etc.
Rule #1 - if the OS is fast, stable and fulfilling its mission let it be! You have little to gain and a lot to lose. Although there was a big security hole in 12, not sure if it was patched already or if the patch is in what you just install. Oddly that hole isn't in 9-11.
Gookill is a mess...

I have the same problem with fingerprint unlocking. It simply doesn't work (if I press the side button, it works). Some hours ago I wiped the system cache and after that, I didn't notice the described problem. I will see in the next few hours.

Now I changed "Fingerprints -> Show icon when screen is off" to "Tap to show" instead of "On always on display" which was the default after the upgrade to Android 13.
UPDATE: The phone still has the same problem. Sometimes it simply doesn't allow it to unlock with a fingerprint. The screen is locked as hell. Only the side button unlocks it.

If you go to Lock screen>Always On Display>Show always, does that solve your problem? Mine was set to "show for new notifications" only and the fingerprint icon would disapperar after locking it.

Mine was set to "Show for new notifications". As you suggested, I changed it to "Show always" and we will see, how it works. In my opinion, it is better to show display only when something happens. But something changed and problems occurred.

Report: it didn't help. I have found out that the issue appears if the phone is locked for a while and then a notification comes. This is the reason why this problem exists also while using Android Auto. It creates a notification when it connects ... and then the phone can be unlocked with a fingerprint until the side button is pressed. I'm sure this is a bug that didn't exist before the upgrade to Android 13.

no such issues here with the eu version. definitely an upgrade in every way.

After 3 days with Android 13 on snapdragon variant, only two minor issues found here : slow charging (2h20 from 0 to 100, less than 2h before) and an "unauthorized action due to modified device" screen when rebooting, disappearing by touching "OK" button. Don't know what is unauthorized but... well. I was rooted before, now stock unrooted and relocked bootloader. It doesn't seems to lock something, everything I use is working.

I have the same fingerprint issues after updating to UI5 (unlocking from turned off screen). Sometimes it works, sometimes it doesn't. It worked perfectly before I updated, didn't change any settings. Very annoying, hopefully it will be fixed in a future update.

The recent update with the December security patch seens to have resolved this issue for me.
